Soda acid extinguisher contains the chemical :

Options

A. `NaHCO_(3)`
B. `Na(OH)`
C. `Na_(2)CO_(3)`
D. `NaCl`

Explanation

**Step-by-Step Text Solution:**

1. **Identify the Components of a Soda Acid Extinguisher:**
- A soda acid extinguisher primarily contains two chemicals: sodium hydrogen carbonate (commonly known as sodium bicarbonate) and sulfuric acid.

2. **Chemical Reaction:**
- When sodium hydrogen carbonate (NaHCO₃) reacts with sulfuric acid (H₂SO₄), a chemical reaction occurs. This reaction produces carbon dioxide gas (CO₂), water (H₂O), and sodium sulfate (Na₂SO₄).

3. **Understanding the Role of the Extinguisher:**
- The purpose of the soda acid extinguisher is to extinguish fires by removing one of the essential elements of combustion: oxygen. The carbon dioxide produced during the reaction helps to displace oxygen around the fire, thus suffocating it.

4. **Mechanism of Action:**
- The reaction between sodium bicarbonate and sulfuric acid generates pressurized water and carbon dioxide. The pressurized water is then expelled from the extinguisher onto the fire, effectively cooling it and removing heat, while the carbon dioxide helps to cut off the oxygen supply.

5. **Conclusion:**
- Therefore, the chemical components of a soda acid extinguisher are sodium hydrogen carbonate (NaHCO₃) and sulfuric acid (H₂SO₄).
